Yes, I think it used to be at the bottom of the pulse of pbs page. It looks like it's gone.

Although "Pulse of PBS" is not something I check very often, it is curious that displaying the number of books mailed each year has been dropped. I doubt this has anything to do with the ability to track the actual numbers, so perhaps TPTB decided this was no longer useful information. But in my opinion, listing the number of books mailed each year would provide insight regarding club growth and activity over the years.

I also remember that the heart on the Pulse page used to actually pulse, whereas now it is a static image.
